Resin composite plus connective tissue graft to treat single maxillary gingival recession associated with non‐carious cervical lesion: randomized clinical trial

Aim To evaluate clinically, the aesthetics and the patient‐centred parameters after the treatment of gingival recession associated with non‐carious cervical lesion by connective tissue graft alone or combined with a nanofilled resin composite restoration. Methods Thirty‐six patients presenting one Miller Class I or II gingival recessions and B+ tooth cervical defect were included. The defects were treated by either connective tissue graft ( CTG : control group; n  = 18) or connective tissue graft plus resin composite restoration ( CTG + RC : test group; n  = 18). Results The mean percentage of defect coverage was 82.16 ± 16.1% for CTG and 73.84 ± 19.2% for CTG + RC after 1 year ( p  > 0.05). Both groups presented statistically significant improvements in two aesthetics evaluations. The professional evaluation ( MRES ) was 7.44 ± 2.3 for the CTG group and 7.52 ± 2.27 for CTG + RC after 1 year, with no significant difference between the groups. The two groups presented significant reduction of dentin sensitivity ( DS ), it decreased from 94.4% of the sites to 44.4% in the CTG group and from 88.8% to 5.5% in the CTG + RC group. Conclusions CTG or CTG + RC can successfully treat gingival recession associated with B+ non‐carious cervical lesion, but less sensitivity may be expected with the combined approach ( NCT 02423473).
